A polyglot is a person who can (usually, fluently) communicate in at least four languages. It is the next term after being trilingual, since the "poly" prefix denotes that the person can communicate in more than three languages.
A famous polyglot would be Pope Leo XIV, who is capable of speaking English, Spanish, Latin, French, Italian, and Portuguese

설현: "Damn I have enough trouble speaking progressivism's oppressor versus oppressed -- I'm surprised she can all those languages of politics. She must be really well read."
